132 F. OVINA; F. DURIUSCULA, L.; P. PRATENSIS, L. 



from the Kew Gardens. Of all the races this one seems the 

 best adapted to the dry prairie regions of the Central United 

 States. 



Festuca ovina, L., Sheep's Fescue. A small perennial, 

 densely tufted, leaves chiefly radical, very narrow, conduplicate, 

 appearing cylindrical, the upper more or less flattened. Panicle 

 one-sided, short; spikelets, 4-10-fld. Glumes faintly nerved. 

 Dry, hilly pastures, very variable. Of little value, but here 

 mentioned because it is so common and likely to be found. 



Festuca duriuscula, L., Hard Fescue. Compared with the 

 preceding, less densely tufted, taller, larger, sheaths downy. 

 Panicle more open, varying much in color. All intermediate 

 forms can be selected from this to the preceding, of which many 

 consider it a mere variety. 



For dry pastures this seems to be worthy of some attention. 



POA, L. 



Spikelets, 2-6-flowered, compressed, in loose or close panicles; 

 bunches, 2-nate or in ^-whorls. Rachilla jointed between the 

 flowers which are perfect, rarely imperfect. Empty glumes 

 unequal, shorter than the lowest floral one, keeled, acute or 

 obtuse ; the lower 1-nerved, the upper larger, 3-nerved. Floral 

 glume often webbed below, keeled, acute or obtuse, 5, rarely 

 7-nerved, tips hyaline. Palea 2-nerved, ciliate. Lodicules tumid 

 below. Stamens 3. Styles 2, short, terminal, distinct, stigmas 

 feathery. Caryopsis avoid, oblong, grooved, free. Annuals or 

 perennials, low or tall, leaves flat or conduplicate. About 80 

 species, chiefly in cold or temperate regions, nearly related to the 

 fescues, having shorter and more compressed glumes, without 

 awns.
